l Claims. (fil- 139-403) This invention relates to improvements in rugs and particularly rugs of the type in which the pile is formed of warp loops, preferably in the form of long twisted loops.

Generally speaking it is old in the art to form a rug having a pile surface of long twisted loops, the loops being of uniform length and arranged in rows with the loops of adjacent rows disposed in parallel or staggered relation with respect to each other. The uniformity of the length of the loops results in the loops assuming a fiat matted position over the base fabric which is dull and unattractive in appearance. The matting down of the loop pile creates a frict on between the loops and fabric base thus decreasing the serviceability of the rug.

The primary object of the present invention is to provide a rug having a pile surface of intermingled long and short twisted loops to produce a relative thick pile surface of irregular appearance which is attractive and appealing to the eye.

A further object of the invention resides in interspersing the short twisted loops among the long twisted loops in a manner to serve as supports for the long loops to maintain the long loops in elevated relation to the base fabric thus eliminating friction and increasing the serviceability of the rug.

A still further object of the invention resides in providing a pile surface for rugs which by the combination of intermingled long and short twisted loops will be relative thick and have a high degree of resiliency so that the pile does not become matted down after constant usage.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, 7

Fig. i is a fragmentary perspective view of the rug with the base fabric extended to show the arrangement of long and short loops,

Fig. 2 is a fragmentary warp-wise cross section of the rug with the base fabric extended. and,

Fig. 3 is a plan view of the pattern card for the loom.

Referring to the drawing wherein for the purpose of illustration 2. preferred embodiment of the invention is shown, the rug is formed of pile warp yarns ii, stufier warp threads 6, double chain warp threads 1 and weft or filler threads 8 and 9.

The pile warp yarn 5 is formed of a multi-ply structure in which each ply is first slack-twisted and then brought together and over-twisted to provide a yarn which is bulky in appearance. As shown in Fig. 2 there are two stuffer warp threads .6 to each pile warp yarn and between each row of pile warp yarn and stuffer warp threads are double chain warp threads I which bind the upper and lower weft threads ii and 9 into engagement with the pile yarn and stufier threads forming a tightly woven base fabric.

Loops ill are formed in the pile warp yarns at spaced intervals by drawing the pile yarns up wardly from the body of the base fabric. The loops of two adjacent pile yarns are drawn relative high to form long loops H while the loops of the next two adjacent pile yarns are not drawn as high thus forming relative short loops It, the rows of long and short loops being alternately arranged over the entire surface of the rug in accordance with the pattern shown in Fig. 3. After the loops are drawn and released they will become twisted as shown in Figs. 1 and 2 by reason of the over-twist in the pile yarn. The loops are drawn up between two of the upper weft threads and the loops of each adjacent pile yarn is drawn up between a different pair of weft threads so that the loops in each warp-wise row is disposed in staggered relation to the loops in the next adjacent row. In Figs. 1 and 2 the base fabric is shown loosely woven for the sake of clearness in showing the arrangement of the long and short loops. Actually the base fabric is tightly woven with the long loops substantially two inches in length and spaced apart in a warp-wise and weft-wise direction a distance not more than the length thereof. The short loops are approximately one inch in length and are spaced apart in a warpwise and weft-wise direction a distance greater than the length thereof. Thus, it will be seen the short loops tend to lie down upon the base fabric in underlying relation to the long loops, the latter being supported by the short loops in an elevated plane to provide a relative thick pile surface having a high degree of resiliency.

By reason of the short loops being interspersed among the long loops the pile texture of the rug is more appealing and attractive in appearance than rugs of the same type having loops of uniform length. In addition the combination of short and long loops provide a resilient pile surface which will greatl prolong the life of the rug. It is apparent the length and spacin of the loops may be varied from the specific ariangement shown in the drawings without departing from the spirit of the invention.

Having thus described my invention, I claim:

1. A rug comprisin a base fabric interwoven with multi-ply pile warp yarns, each of the plies of which is slack-twisted, the pile yarns being raised upwardly to form rows of long twisted loops and intermediate rows of short twisted loops, the long loops being spaced apart a distance not greater than their length and the short loops being spaced apart a distance greater than their length, the loops of each row being disposed in staggered relation to the loops of the next adjacent rows.

2. A rug comprising a base fabric interwoven with multi-ply pile warp yarns, each of the plies of which is slack twisted, the pile warp yarns being raised upwardly from the fabric to form long and short twisted loops, the long loops being spaced apart a distance not greater than their length and the short loops being spaced apart a distance greater than their length and interspersed among the long twisted loops in underlying relation thereto.

3. A rug comprising a base fabric interwoven with multi-ply pile warp yarns, each of the plies of which is slack twisted, the pile warp yarns 4 being raised upwardly from the fabric to form rows of long twisted loops and intermediate rows of short twisted loops, the loops of each row being spaced apart and arranged in staggered relation to the loops of the next adjacent row, said short loops being spaced apart a distance suiiicient to allow the short loops to lie down in underlying relation to the long loops.

4. A rug comprising a base fabric interwoven with multi-ply pile warp yarns, each of the plies of which is slack-twisted, the pile warp yarns being raised upwardly to form rows of long twisted loops, the loops in each row being spaced apart'a distance not greater than their length, rows of short twisted loops intermediate the rows of long loops, the short loops in each row being spaced apart a distance greater than their length whereby the short loops will lie clown in underlying relatlon to the long loops.
